Re: Man and sloper come a cropper.

Chris really glad you are home and on the mend. Its hard enough looking around and riding defensively in case of bad drivers without simultaneously looking at every dip in the road for pot holes. Hope your bike gets mended soon.My Ariel was half crushed by a van about 4 years ago and my friends neve...

Re: solex - poor mpg

I eventually found my original problem was that the timing had slipped on the distributor, probably on that run on new years day. Took a while to figure it out but trial and error got the bike working properly again. In future I will use the fully advanced position for timing as I think the static t...

Re: Sq 4 MK II (Solex) Reluctant to cold start

Paul
when you get the bike running what happens if you apply the bi-starter when warm?
If the answer is no change, then the bi-starter must not be functioning as the bike should instantly stall

Re: solex - poor mpg

Well at long last I have pulled the carb off and inspected it. The air correction jet looked partially blocked so I blew some air down it which seemed to clear it. I then (for some reason not even known to me) blew air down the other end and then it looked restricted again - couldn't see daylight wh...

Re: solex - poor mpg

Chris thanks for the advice. I think the dimple you mention refers to the section on the top of the float which has a sort of dimple but mine is a greater depression within that caused by wear. I will certainly give the idea of changing washers a go as in the past I have noticed that the bike does i...

Re: solex - poor mpg

actually - thinking about it I believe I have another better condition float kicking around in the garage so I will make a substitution and see if there is a difference. The bistarter needs full choke on cold but soon goes back in - less then a minute. Still I will check it is not sticking and fully...

Re: solex - poor mpg

thanks for the replies. I will have to check engine braking next time im out on it but I don't think it is overly noticeable. One thing I must pay attention to is the float height though, as the contact point on the float to the shut off valve is a bit concave from wear. I had thought of applying a ...

Re: solex - poor mpg

Thanks Bob
I was hoping for 40+ mpg at least.
Not sure how these carbs respond to ultrasound cleaning and the like - wondered if that might help

solex - poor mpg

I took the square 4 for a blast on new years day covering over 70 miles at speeds between 50 and 70mph On the way home I had to hit reserve despite having a good few gallons above the reserve line prior to the journey. I estimate I was getting around 35MPG or so. No leaks - not an overly rich mixtur...
